ESTA(アメリカ電子渡航認証システム)、切れそうになるとメールで教えてくれるのか！

さっきこんなメールが来た。調べてみると、、、おお、確かにESTA来月期限が切れる。

件名: ESTA Expiration Warning

ATTENTION! The travel authorization submitted on August 15, 2014 via ESTA will expire within the next 30 days. It is not possible to extend or renew a current ESTA travel authorization. You will need to apply for a new ESTA travel authorization. Please reapply at https://esta.cbp.dhs.gov if travel to the United States is intended in the near future. If there are 30 or more days left on the old authorization you will receive a warning message during the application and be asked if you wish to proceed.

ESTA切れてるの知らないで海外出張しようとして渡航できなかった人を何人か知ってる（一人は私のボスだ）。 これはありがたい。早速登録しなおそう。
